SPECIFICATION forming part of Letters Patent No. 759,078, dated May 3,1904.

Application filed March 19,1903- To 00% whom it may concern.-

Be it known that I, DAvID CRAIG, a citizen of the United States,and aresident of Melrose, in the county of M iddleseX and State ofMassachusetts, have invented new and useful Improvements in Urinals, of'which the following is a specification.

My invention relates to urinals; and its object is to provide animproved urinal capable of eifectively collecting and carrying away thegases which arise from the bowl, of protecting from injury by oxidationor corrosion the waste-pipe fittings or other piping or metalwork belowthe urinal, and containing other useful features hereinafter pointedout.

Urinals of the class to which my invention relates usually consist of aporcelain bowl, the back of which is flat and adapted to be fixed inposition against the wall. It is usual to provide a perforated pipeextending around the edge of the opening of the bowl or urinal, throughwhich the bowl may be flushed at intervals by admitting water to thepipe. Heretofore it has also been usual to provide a vent in the backwall of the bowl, but below the flushing-pipe, communicating with aventilatting-pipe leading to the exterior of the building for thepurpose of carrying away the gases which collect in and arise from thebowl. The location of this ventilation-opening below the flushing-pipeis objectionable, for the reason that the water discharged from theflushing-pipe flows across the opening and closes it, thus interferingwith the draft and cutting olf the entrance of the gases into theventilator for the time being. FuItllGlIllOlG, the water enters the ventand tends to soil it, both by leaving deposits of whatever sediment maybe in the water and by constantly wetting it, so that it is in conditionto accumulate dust and dirt, which adhere to the wet surface and notonly disfigure the urinal, but necessitate fre quent cleaning. Anotherdefect in the present construction of urinals is that the metal piping,coupling, and other fittings below the bowl are exposed and unprotected,the result being that moisture flowing or dripping down upon the outsideof the bowl reaches the metal fittings and corrodes and oxidizes thesame, tending to disfigure and ultimately to destroy Serial No. 148,514.(No model.)

them. Still another defect in the present construction of urinals is theabsence of any device to perfectly collect the gases arising from thebowl and to direct them into the ventilator-opening in such manner as toinsure their removal. Without such provision only part of the gases willfind their way into the ventilating-opening and the rest will pass offinto the air of the room. To overcome these objectionable features, Ihave provided the bowl of my improved urinal with a w 11tilating-outletlocated above the water-outlet of the flushin g apparatus and outside ofthe path of How of the water, so that the passage of the water down theback of the bowl in no way interferes with the draft through theventilating-opening nor tends to foul the same. I have also provided askirt or shield. depending from the bowl to conceal and protect thepiping, &c., below the bowl from drippings descending the outside of thebowl. I have also provided a hood or canopy at the top of the urinal andextending substantially over the bowl to collect the rising gases anddirect them into the ventilatingopening, thus insuring more perfectventilation than has heretofore been secured.

In the accompanying drawings, Figure .1 illust "ates a central verticalsection of a urinal embodying my invention, and Fig. .2 illustrates afront elevation of a urinal embodying my invention.

Like parts are indicated by like letters of reference in both figures.

A represents the bowl of the urinal, of which the back wall (4 is madeflat, so as to be parallel with the wallagainst which the urinal isplaced. (he top edge of the bowl is bordered, as usual, by a pipe 11/,which is perforated at intervals throughout its length upon the inner orlower side. The pipe (1/ communicates with a port 0?, which is connectedby a pipe (not shown) with a supply of water, and this port (0 opensinto a pipechamber of, extending vertically behind the wall (0 of bowl Aand inclosing the pipe (not shown) that is connected with-port e Aseries of separated annular rims a are also formed upon the under sideof the bowl A, constituting one member of a coupling, the other memberof which is not shown, but

may be on the end of a metal pipe leading, as usual, through a siphon toa sewer.

Integral with the bowl A and upon the bottom thereof is a dependingskirt or apron B, which extends around annular rims a and the end of thewaste-pipe and its couplings. The moisture flowing down the outside ofbowl A is deflected and prevented from reaching the coupling or themetal piping located below the urinal. Moreover, the pipe connectionsbelow the bowl, which are unsightly unless costly and finely finished,are hidden from view, and therefore do not need to be as ornamental asheretofore required. The skirt or apron B is open at the bottom topermit free access to the pipe connections for the purpose of repair andto permit easy coupling of the waste-pipe. Skirt B extends around infront of the pipe-fittings, but is open at the back, the ends abuttingagainst the wall.

At the top of wall a is provided a short extension (0*, and through thisextension is provided the ventilating-outlet C above the flushing-outleta and removed from the path of the flow of water. As will now beobvious, its location above the pipe 0 makes it impossible for the waterdischarged from said pipe to interfere in any way with the draft throughsaid outlet, and also makes it impossible for deposits of foul matter tobe left in said outlet by the water crossing it as heretofore, and bykeeping it dry lessens the accumulation of dust and dirt therein.Furthermore, the outlet 0 being located above the flushing-inlet insteadof in the rear wall of the bowl may be of any size and is not limited tothe size of the rear wall of the bowl.

A hood 0 at the top of the urinal overhangs the bowl A, and like aninverted funnel tends to collect and gather in the gases arising fromthe bowl. This hood is preferably formed integral with the extension(4*,

and extends substantially over the bowl, providing, in effect, anenlarged opening of the ventilating-outlet, the mouth of which is thuscarried forward to a point directly over the bowl.

hat I claim is- 1. As a new article of manufacture an integral urinalcomprising a bowl made with an outlet through its bottom; a dependingskirt surrounding and shielding said outlet; said skirt being open atthe bottom, a hood at the top of and overhanging the bowl, and aventilating-outlet leading backward under the hood and through the rearwall of the article.

2. As a new article of manufacture an integral urinal comprising a bowlmade with an outlet through its bottom; a depending skirt surroundingand shielding said outlet, said skirt being open at the bottom; a hoodat the top of and overhanging the bowl, a ventilating-outlet leadingbackward under the hood and through the rearwall of the article; awater-inlet port under the ventilating-outlet and leading backwardthrough the rear wall of the article, and a perforated pipe around theperiphery of the bowl communicating with said port.

3. The new article of manufacture above described made up of the bowl A;ventilatingoutlet 0 through the rear wall of the article; the hood 0above outletC and projecting over the bowl A; the port (0 openingdownwardly into the pipe-chamber 0/ behind the bowl A; and pipe-chamber(6 the pipe a communicating with port (0 and the depending skirt B openat the bottom.
